Krtkus

An extended 5x12 keyboard with 2 extra keys. The design is intended for ortho layouts with a shifted number row, allowing for the placement of the delete and tilde keys above their usual spots. PCBs are designed in Kicad, case in Blender.

• Low profile
  • Kailh Choc V1
  • Gateron KS-27/KS-33
• QMK/VIA compatible
• Tray mount
• 3D printed case with a 7 degree tilt

To connect the keyboard to usevia.app, the design file has to be manually uploaded in the design tab.
